Pathophysiologic findings in nonretarded autism and receptive developmental language disorder.

摘要: In nonretarded autistic, receptive developmental language disordered, and normal subject groups, we recorded in auditory visual target detection tasks two neurophysiological components of the event-related brain potential, Nc P3b. Existent research shows that, normals, P3b appear early development, are associated with attention memory processes, endogenous which means that they triggered by internal, consciously initiated attentional cognitive mechanisms can be even theomission sensory stimulation so long as it has meaning or importance for subject. this report, were response to omission stimulation. Consistent hypothesis autism involves abnormal responses important information, was found smaller than small often absent autistic group under condition when no processing required.
